ICP Gas Valve Support Bracket for RGS120HRAA0AGAA | Ships Today

Overview

This is the genuine OEM gas valve support bracket, part number 1178238, for the ICP / Tempstar / Heil RGS120HRAA0AGAA gas furnace. This is a mounting bracket, not the gas valve itself. The bracket holds the gas valve rigidly in place within the burner assembly, maintaining correct alignment between the valve, manifold, and burners. A bent, corroded, or missing bracket allows the gas valve and manifold to flex, which can stress gas-line connections and misalign the burners.
